Since 1980' s, the consumption of clay in the world has been on the rise. In 2002, the consumption of clay in the world reached 45 million tons (25 million tons for paper industry), and that in Japan, South Korea and Southeast Asia was about 8000 ~1000 million tons, but most of the clay in these countries and regions depended on imports. At present, there are more than 60 countries producing kleit in the world, and the countries with relatively large output are the United States, Britain, CIS, South Korea, Brazil, Germany, Czechoslovakia and China. The coal output of the above eight countries accounts for about 80% of the world's total output. The annual output of the United States is 8.87 million tons, the annual output of the United Kingdom is about 2.42 million tons, and the annual output of Brazil is 65438+700,000 tons. Potash deposits suitable for paper grade in the world are mainly distributed in the United States, Britain, Brazil, Australia and other countries. At present, coal-series calcined lignite is not produced abroad, and its calcined lignite products are mainly made of soft lignite. The production of burnt Klaette in the United States began in the early 1970s, and by 1999, the output had reached 2 million tons, accounting for 1/5 of its final output and 80% of the final output of burnt Klaette in the world. Due to the development of high-quality potassium salt resources in the United States and Britain for many years, the mineral resources are limited, but the development of output is limited. The consumption of white clay in the world is mainly concentrated in papermaking, ceramics, coatings and plastics, and the consumption of white clay used in papermaking accounts for more than 50% of the total consumption worldwide. The United States is the largest consumer, followed by Western Europe. 60% of Clete's production in the United States is used in the paper industry (paper coating accounts for 40%, filler accounts for 20%), building materials account for 20%, refractory bricks and olive fibers 16%, paints and plastics account for 4%; 80% of Clete's output in Britain is used in the paper industry. The consumption pattern of China's clay is quite different from that of foreign countries, with a total consumption of 800,000-900,000 tons, and ceramics and refractories account for 80% of the total. Most of these two industries buy clay ore nearby and use it directly, so the product scale is relatively low. However, the paper industry consumes 200,000-220,000 tons of white clay every year, which can only meet about 90,000 tons in China. The main reason is that the reserves of soft white clay suitable for paper coating in China are insufficient. In order to change this situation, it is necessary to develop and utilize coal-series kaolin resources, develop the production of burnt kaolin, and realize the self-sufficiency of horizontal kaolin for paper coatings in China. Coal-series kaolin is a unique kaolin resource in China, which is mainly distributed in the black coal-Permian coal-series strata in northern, northeast and northwest China. China began to develop coal ashing from the early1980s, but the large-scale industrial production began in the early1990s, and there were few manufacturers and small scale. At present, there are dozens of factories producing anthracite in Shanxi, Inner Mongolia, Shaanxi, Anhui, Jiangsu, Ningxia, Xinjiang and Northeast China, but there are only a few large-scale factories that can produce high-quality anthracite, with an annual output of less than 654.38 million tons. 2. 1.2 Market transactions At present, the annual trading volume of clay in the world is about 8 million tons, 80% of which is used for papermaking, 15% for ceramics and 5% for others. Klaette's main export countries are Britain, the United States, Brazil, China and so on. The export volume of kleit in the United States does not account for 45% and 30% of world trade, and it has been controlling the international market for many years. The export products are mainly Earth and modified Earth. The main importing countries are Japan, Germany, Italy, Canada, Finland and France. This year, the daily import volume accounts for about 16% of the world trade volume, and it is the largest consumption market for cod in Asia, with an annual import volume of over 65,438+200,000 tons, most of which are imported from the United States and Brazil. The shipping cost from the United States to Japan is about 100 USD per ton. Most of kleit exported from China are processed and beneficiated primary products (washing soil) or not beneficiated. Since the late 1980s, China's foreign trade export has been expanding day by day, rising to 440,000 tons in 1995. The main export targets are Hongkong (73.5%), Japan (10.6%), Malaysia (10.6%) and Taiwan Province (5.39%), most of which are raw ore, and the sales price is low. At present, the demand for pigment minerals such as white clay used for papermaking in China is 700,000-800,000 tons/year. Due to the shortage of high-quality white clay in China, it has to be imported or replaced by other mineral colors. In recent years, the import burning loss of China's paper coating industry is137,200 tons in 1996,154,300 tons in 1997,164,300 tons in 1998, and 1999/05,200 in 2000. The general trend of Clete price is. The price of coating and ceramic layer is stable, while the coating layer is accelerating. See table 2- 1 for various kleit prices of British and American D.B.K and THIELEkleit companies. Supplementary question: Japan, South Korea, Southeast Asian countries and Hong Kong and Taiwan, which are close to China, do not produce high-quality clay and burnt clay, or the output is very small, so they must import a large number of high-quality clay (including selected clay and burnt clay) products from the United States, Brazil, Britain and other countries. Only Japanese, Taiwan Province, Korean and Indonesian imported high-quality cod from American countries, reaching 103.794, 14.593, 1 1.59 and 68,460 tons respectively. Together with the import volume from Brazil and other countries, the total annual import volume of Klaette in Japan is over 65,438+200,000 tons. Compared with the United States, Brazil, Britain and other countries, China is close to Japan, South Korea, Southeast Asia and other countries and regions, occupying a geographical advantage. It arrives in Japan with a freight of not more than $35 per ton, while the sea freight from the United States to Japan is $0/00 per ton, which has a competitive advantage in price. It is entirely possible to enter the Japanese and Southeast Asian markets. Therefore, with the progress of processing technology, the steady improvement of product quality and the expansion of production scale, China began to export high-quality roasted eel to Japan, South Korea, Southeast Asian countries, Hong Kong and Taiwan and other neighboring countries and regions. It is estimated that the export volume reached about 70,000 tons in 2007 and about 250,000 tons in 20 10.

I'm impressed with you. I only give people five points for translating such a long article. How stingy!
